“…It has been shown that sagitta morphology is an informative tool in taxonomic and systematic studies of some fish taxa (e.g. Bani et al, 2013;Fortunato et al, 2014;Ghanbarifardi et al, 2020;Gierl et al, 2018;Jawad, 2007;Purrafee Dizaj et al, 2020). Moreover, it can be used in studies related to ancient fish faunas in palaeontology (e.g.…”

Hidden taxonomic characters in otoliths of blenniid fishes (Teleostei: Blenniidae) from the Iranian coasts of the Persian Gulf and Oman Sea ecoregions: A scanning electron microscopy approach

et al. 2021

In the present work, the morphological characteristics of sagitta were described and analysed for 10 species of combtooth blennies (Blenniidae) inhabiting the intertidal region of the Persian Gulf and Makran zone of Oman Sea to see the taxonomic usefulness of otoliths, especially their hidden characters for species identification. Based on the obtained results, sagitta morphology could be considered as diagnostic characters distinguishing the genera Alticus, Antennablennius, Istiblennius, Omobranchus and Parablennius showing differences related to general shape, that is, elliptic/oval to triangular; shape of antirostrum and its degree of development; the degrees of convexity of ventral and dorsal margins, and shape of ostium. The common/general otolith characters shared in the all studied combtooth blennies, is the heterosulcoid condition, which is a shared character with Perciformes and Gobiiformes. The type of sulcus is ostial, and it can be considered as a plesiomorph character shared with a basal group of actinopterygian fishes. The obtained results could be useful in taxonomical, paleontological, ecological and food and feeding habits studies.

“…Otoliths are calcareous concretions located in the inner ear of fish and are species specific (Campana 1999;Assis 2000;Tuset et al 2003a). Otolith shape is a tool widely used for taxonomic studies (Volpedo and Echeverría 1999;Tombari et al 2005;Tombari et al 2010;Volpedo and Vaz dos Santos 2015;Jawad et al 2017), fish stock identification (Avigliano et al 2015a), nursery areas identification (Avigliano et al 2016(Avigliano et al , 2017, discrimination among closely related species (Callicó Fortunato et al 2014;Avigliano et al 2015bAvigliano et al , 2018, ecological studies (Avigliano et al 2014(Avigliano et al , 2015c and ontogenetic studies (de Carvalho et al 2015;Callicó Fortunato et al 2017).…”

The study of otolith morphometry is a tool widely used in numerous studies of fish populations (fish stocks, taxonomic, ecological, ontogeny, among others). The aim of this study was to detect ontogenetic variations in the otolith of Odontesthes argentinensis through the application of traditional and geometric morphometry and the association of these variations with ecological and trophic habits of the species. Fish (52 to 360 mm TL) were collected seasonally between years 2013-2016 in the southwest coast of the Atlantic Ocean (36°39'30.96"S -56°40'40.09"W). Otolith shape indices (circularity, rectangularity, aspect ratio and surface occupied by sulcus) and Fourier descriptors were measured and compared through ontogenetic stages (I, II and III). The three stages analysed in the present study were differentiated by both traditional and geometric morphometry. The four analysed indices showed significant differences between stages (ANOVA Kruskal Wallis test, P < 0.001) and a simultaneous analysis of the morphometric variables also showed significant differences (Hotelling's T 2 < 0.001). The quadratic discriminant analysis performed on the Fourier descriptors showed a clear separation for each defined group. Therefore, the use of both methodologies simultaneously could be considered robust to evaluate the ontogenetic variations in this species. The observed changes could be associated to changes in the habitat throughout its development, to the sexual maturity of fish and to dietary shifting of these organisms.

“…The morphometry and morphology of the otoliths have been widely used to identify species of other families. For example, Callicó Fortunato et al (2014) have used the morphometry to identify species of mullets (Mugilidae) from the North-eastern Atlantic and Mediterranean Sea, while Tuset et al . (2008) performed the characterization of 348 fish species using otolith morphology and morphometry.…”

Assessment of the morphometry of saccular otoliths as a tool to identify triplefin species (Tripterygiidae)

2015

In the present work we describe nine saccular otolith morphometric indices (circularity, rectangularity, aspect ratio, percentage of the otolith surface occupied by the sulcus, percentage of the sulcus length occupied by the cauda length and ostium length, otolith length relative to the length of the fish, rostrum aspect ratio and percentage of the rostrum length occupied by the otolith length) of 41 species of the Tripterygiidae family collected mainly from New Zealand, Australia, Chile, South Africa, Mediterranean Sea and North America. The principal component of analysis showed that the indices that best explain the variability between species were related to sulcus and rostrum morphometry. According to cluster analysis, otolith morphometry could reflect the diversity of microenvironments for some genera such as Notoclinops and Forsterygion, while this does not happen to genera like Enneapterygius and Ruanoho. The discriminant analysis showed that the species Helcogrammoides cunninghami, Karalepis stewarti, Lepidoblennius haplodactylus, Notoclinus compressus, Ucla xenogrammus can be discriminated by using the morphometric indices. Two new indices related to the sulcus that were of great value for the discrimination of these species are described for the first time. This information will be a useful tool for palaeontological, taxonomic and trophic ecology studies.
